BUTTON-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 582,? 59, dated May 18,1897.

Application filed February 9, 1893. Serial No. 461,593. (No model.)

To all 1071,0772, it nut l concern/.-

Be it known that I, WILHELM NAGEBORN, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a certain new and useful Improvement in Button-Making Machines,of which the following is a specification.

The object of my invention is to reduce the cost of manufacturingbuttons, especially those made from mother-of-pearl, although my machineis applicable to the making of buttons from bone, vegetable ivory, andthe like; and my invention is an improvement upon machines havingarotating table or support carrying the button-blanks, and particularlyupon the machine invented by myself and George Carlyle, upon which anapplication for Letters Patent was filed May 23, 1892.

In carrying out my invention I provide a machine having several toolsperforming different operations which act upon two or more button-blankssimultaneously, each blank being operated upon by the different tools insuccession,such machine being so constructed and arranged in its severalparts that the blanks can be delivered to and removed from the machinewith rapidity, and the several operations can be performed quickly andwithout unnecessary loss of time.

In its general features my machine consists of a series of travelingbutton-blank-holding chucks traveling, preferably, over and under oraround a stationary table or support, the chucks being opened and closedat the proper intervals by the forward movement of the whole series.Above these traveling chucks and in line therewith are supported therotating forming, centering, and drilling tools. These tools are held inchucks placed upon rotating spindles which are capable of a verticalmovement toward and away from the traveling button-holding chuckssimultaneously, which movementis imparted to them by a suitable framewhich also acts as an end bearing for the spindles. This frame isdepressed by a lever moved by the operator to bring the tools inposition to act upon the blanks simultaneously, and when the operationis performed the frame and tools are returned to their normal positionsby the pressure of the springs coiled around the spindles. The upwardmovement of the lever operates to release the pawls engaging with thetraveling buttonholding chucks and operates the mechanism for movingsaid chucks, so that upon the next downward movement of theoperating-lever the respective tools will act upon the next blank. Thusthe different tools will act succcssively upon each blank andsimultaneously upon different blanks. At the point where the blank is tobe placed in the chuck the chuck rides over a cam situated in its path,which gives it an outward movement in its block, thus allowing its jawsto open. The blank is then inserted, and as the chucks are shifted alongby the return movement of the operating-lever the one which has justreceived a blank rides off the cam and is forced backward in its blockby means of a spring. The blank is then firmly held by the chuck. Torelease the completed button, the chuck rides over a similar cam placedso as to operate at a point under the table, so that when the grip onthe button is released the button will drop out.

In the accompanying drawings, Figure 1 is a front elevation of themachine; Fig. 2, a partial cross-section and side elevation; Fig. 3, atop plan View, the tool spindles and supports and frame being omitted;Fig. 4: a central longitudinal section of the table and blocks of theblank-holdin g chucks,the chucks being shown in elevation; Fig. 5, aseparate elevation of the table and blocks of the blankholding chucksand of the notched wheels which impart motion to the chucks; Fig. 6, anelevation taken on the line 6 6 of Fig. looking in the direction of thearrow, some of the parts being omitted; and Fig. 7 ,a section throughone of the button-blank-holding chucks.

A is the table or support, constructed, preferably, of the form shown,and over or around which the blank-holding chucks B travel.

B are the chuck blocks or seats.

The table or support A in cross-section is constructed in the form ofthe letter H, as shown in Fig. 2, and rounded at the ends, as shown inFigs. 1 and 4. The side as has a flange so all around it which fits intoslots 4) 011 the blocks 13. The other side of the table y has a channely all around its outer side, and in this channel travel pins 10, whichare rigidly held in the extensions wof the chuckblocks 13. The chucksextend between the sides of the table, and on the web .2, connecting thesides of the table, are formed the cams tand t, before referred to. Thechannel 3 and pins it serve to guide the chucks and seats around thetable and also prevent them from falling awayfrom the table as they passunder it.

C are the spindles carrying the tools 1 to 5 and rotated by beltconnection with the pulleys C, and D are the bearings through which thespindles work.

The bearings D are secured by screw-bolts to the supports E and E, sothat the spindles may be given different positions relative to thebutton-blanks, as shown in Fig. 1.

F is the frame by the depression of which the tools carried by thespindles are brought into operative position.

The operating-lever G is pivoted at a to the post (Land is provided witha rounded lug b, resting on the lower cross-bar of the frame F. At theshort end of the lever is a socket in which is placed a spring-projectedpawl c, which engages with the ratchet-teeth e on the gear-wheel d. Thewheel (I meshes with the pinion d, which pinionimeshes with the pinion(Z on the shaft 6. The shaft 6 passes through the table A and carriesthe notched wheel f. A similar wheel f, Fig. 5, is carried by the shaft6', mounted in bearings at the opposite end of the table. The notches gon these wheels engage with the pins h on the seats of the travelingchucks. Under the top plate of the machine is a rock-shaft 1, supportedin bearings 7a. This shaft carries locking-dogs Z and l, which extendthrough openings in the top plate and engage with the notches m in thechuck-blocks 13. Projecting downwardly from the rock-shaft 2' is an armn, and between this arm and post a is placed spring 0. This spring actsto throw the dogs Z and Z into the notches m. Pivoted at p on the leverGis a dog 1'), whichis thrown forward by a light spring q, secured tothe lever G.

The bntton-blan k-holdin g chuck is formed, preferably, of three jaws,tapered on their outer surfaces for a portion of their length and heldtogether at their lower ends by a collar '1'. An opening is formedthrough the center of the chucks into which the d rillin g-tools enterafter passing through the blanks. \Vhen each chuck rides up onto the cami, it is forced outward and the jaws of the chuck will separateslightly, and the button-blank is then placed in the recess u. A springS is coiled around the cylindrical portion of each chuck between thecollar 9' and the under side of the chuck-blocks, and when each chuckrides off the cam the spring forces the chuck back into the block, andby reason of the taper given the jaws of the chuck and the correspondingincline of the block the spring action will wedge the jaws togetheruntil they have a firm hold on the button-blan k. \Vhen each chuck ridesup onto the cam t the same action takes place and the button will dropout.

The operation of the machine is as follows: A blank is inserted in thechuck which is at the moment on the cam 15 and the lever G is moveddownward. The downward movement of the lever will cause the frame F tomove downward, and consequently the tools 1 to 5. As will be seen inFig. 2, the dog 12 is held against the arm n by the spring (1 when thelever G is in its normal position. The pressure of the dog p against thearm n in this position does not affect it, as the spring is of much lesstension than the spring 0. In moving the lever G downward the inclinedmeeting surfaces of the dog 1) and arm n will slide past each other, andas the dog 12 clears the arm n the spring (1 will throw the dog 1) tothe forward limit of its movement. The position of the lever G and thepawl c and dog 9) are now as shown in dotted lines in Fig. 2. This isthe position when the tools are operating upon the blanks. There being,however, no blanks under the tools the lever is returned to its normalposition to shift to the nextposition the chuck which has just receiveda blank. That is accomplished by raising the lever G, causing the pawl cand dog 1) to act simultaneously upon the teeth 0' and arm 72,respectively. The pressure of the dog 1) upon the arm 11 starts thepawls Z from the notches, and the power exerted on the wheel (I, throughthe teeth 0' and pawl 0, will rotate the wheel f, and consequently shiftthe blocks 13. The pawls Z and notches m being wedge-shaped the dog 1)simply acts to start the pawls l by its upward pressure on theslightly-curved end of the arm 'n, the pawlsl being forced entirely outof the notches by the shifting of the blocks 15. In the meantime the dog2) will have been forced backward against the pressure of spring g bythe further movement of the lever G, this being accomplished by theinclined meeting surfaces of the arm n and dog 17. The pressure of thespring 0 will keep the pawls 1 against the blocks 13 and force them intothe notches of the succeeding blocks when they have been moved theproper distance. The next chuck is then in position to receive a blank,and as the lever G is moved downward tool 1 will operate upon the firstblank inserted. \Vhen the operation is completed, the lever is returned,with the same result as before. This will place another chuck inposition to re ceive a blank, and upon moving the lever downward againtool 2 will operate upon the first blank and tool 1 will operate uponthe second. \Vhen this operation is completed, the lever is returned, asbefore, to its normal position and another chuck stands ready to be fedwith a blank and the operation repeated. \Vhen the first blank insertedhas been operated upon by tool 5, it is ready to be dropped from thechuck, and this is done when the chuck rides onto the cam t.

I do not limit myself herein to the use of the precise form of the tableand button-holding chucks shown and described, as the same may bealtered without departing from the spirit of my invention. Instead ofthe flat table shown a circular or oval-shaped support for the chucksmay be employed, the operating-tools being placed at the proper angles.
